Realizing that chemotherapy can result in renal damage, the nurse should:

Rationale:

A. Hair loss is a common and visible side effect of many anti-neoplastic drugs, but it is not life-threatening. While it can affect self-esteem and quality of life, it does not endanger the patient’s health.

B. Electrolyte imbalances can occur due to chemotherapy, vomiting, or tumor lysis syndrome, and they require monitoring and correction. However, they are usually manageable with fluids and medications and are not the primary life-threatening risk of anti-neoplastic therapy.

C. Bone marrow suppression (myelosuppression) is the most dangerous side effect of anti-neoplastic drugs because it reduces the production of white blood cells, increasing the risk of infection; red blood cells, causing anemia and decreased oxygen delivery; and platelets, increasing the risk of bleeding. Severe myelosuppression can result in life-threatening infections, hemorrhage, or hypoxia, making it the most critical adverse effect to monitor and manage.

D. Although common and distressing, nausea and vomiting are generally manageable with modern antiemetics and are rarely directly life-threatening.

Rationale:

A. Reviewing their medical history and medications is correct because nutritional status in cancer patients can be affected by multiple factors, including prior illnesses, treatments (like chemotherapy or radiation), surgeries, and medications that influence appetite, digestion, absorption, or metabolism. Assessing these factors helps the nurse identify risks for malnutrition, weight loss, or specific nutrient deficiencies.

B. Monitoring their blood pressure is incorrect because blood pressure primarily reflects cardiovascular and fluid status, not nutrition. While extremely malnourished patients may develop hypotension, blood pressure alone is not a reliable indicator of nutritional status.

C. Checking their urine output is incorrect because urine output reflects kidney function, hydration status, and fluid balance rather than protein, calorie, or micronutrient intake. Normal urine output does not mean the patient is nutritionally adequate.

D. Assessing their lung sounds is incorrect because lung sounds evaluate respiratory function and the presence of conditions like pneumonia or fluid overload. They do not provide information about caloric intake, protein stores, or vitamin and mineral deficiencies, which are key indicators of nutrition.
